What's a good Android game to kill some time without needing a fancy controller or complicated rules?

Look, I don't have time for games that require a manual the size of a phone book. Rollance is straightforward – you're rolling a ball, avoiding obstacles, and grabbing points. Easy to pick up, but surprisingly challenging. The levels are short enough that you can play a few while waiting for the coffee to brew, or during a quick break from work. It's not gonna win any awards for graphics, but it's a solid time-waster that doesn't require a ton of brainpower. Honestly, sometimes that's exactly what I need after a long day of dealing with spreadsheets and demanding clients. Plus, it's free, so you can't really complain. If you're looking for something simple and addictive, give it a shot. Might just surprise you.
